Most people stop their fast too soon... A study published in Nature Metabolism (PMID: 38429390) followed 12 healthy people who completed a 7-day, water-only fast. The researchers tracked approximately 3,000 proteins and discovered a massive biological shift that occurred around day three...

The first time most people attempt a multi-day fast, the mental clarity almost never arrives when they expect it to. Chris Hemsworth learned this on his first four-day fast. He had been told the sharpness would kick in by day two or three. Instead it stayed quiet until the afternoon of day four, right as he went spearfishing, and then everything suddenly locked into place. That lag is the real lesson. Ketosis and the associated mental shift do not run on a fixed timetable. For a large number of people the meaningful change only lands on day three or four, and the difference between forcing the process and letting the body arrive on its own often decides whether the fast feels useful or just punishing. Science backs the variation. Most people reach nutritional ketosis within 24–48 hours, but full cognitive and metabolic adaptation commonly continues into day three or four and depends heavily on prior diet, activity level, and individual metabolism. Treating the timeline like a rigid schedule is one of the fastest ways people talk themselves out of finishing. I stopped treating fasting days like a checklist years ago. The interesting part only starts once you stop arguing with the body’s own clock.

Bitwise CEO: There's a tempo mismatch that most crypto natives are missing. In crypto, "an hour is fast. A day is pretty fast. A week is a meaningful time frame, and nobody can remember what happened 4 weeks ago." But the mainstream investor now entering the space? For them a month is really fast and a year is a reasonable time frame. They move at a completely different pace. The progress is real - it just doesn't feel like it to people used to measuring time in hours. FT Hunter Horsley MR SHIFT 🦁 Bitwise.

Valar has often been criticized for its fast pace. They say you can't go fast in nuclear... So I asked my friend Darren to sit down with three people who have half a century of experience in nuclear programs all over the world, and ask them a question: Are we going too fast?

Dr. Mindy Pelz laid out a practical fasting schedule: - 3-day water fast twice a year (e.g. January & September) to clear senescent cells - 48-hour fast once a quarter for mental health & mood - 36-hour fast once a month if weight loss is stuck 24-hour fast once a week as a baseline - Shorter daily windows (12–17 hours) the rest of the time, adjusted around your cycle Prolonged fasting (48–72 hours) significantly ramps up autophagy and stem cell regeneration. Valter Longo’s research shows periodic 3-day fasts or fasting-mimicking diets can reduce biological age markers. Shorter fasts (24–36h) improve insulin sensitivity and fat loss. Different fasting lengths trigger specific benefits, from cellular cleanup to better mood and metabolism. What fasting schedule have you found works best for you?

The best golfers in the world all follow the same approximate swing tempo. A smooth backswing that takes approximately three times longer than their downswing. The truth is, this is easier said than done and the swing tempo of most amateur golfers is way too fast. CHAPTERS 0:00

Is This The Collapse We Have Been Warned About For Decades? A new study published in Nature Climate Change by researchers at Utrecht University reports that the Atlantic Meridional Overturning Circulation survived 5°C of warming in one model run and collapsed at 2°C in another — with the only difference between the runs being how fast the carbon dioxide was added. Lead author René van Westen identify a critical warming rate of roughly three-tenths of a degree Celsius per decade, which their own institution describes as a pace the world is already approaching.

Dana White did an 86-hour water fast, and he says it changed how he sees his body. He went in after learning about Boston studies on prolonged water fasting. According to him, after 72+ hours your body starts shedding dead cells, generating new ones, and fighting inflammation and disease. He came out shredded with insane mental clarity and described hitting a zen-like euphoric state. Research shows that autophagy (cellular cleanup) significantly ramps up between 48-72 hours of fasting. Studies, including recent multi-day water fast trials, have found widespread shifts in thousands of proteins affecting metabolism, inflammation, immune function, and even brain-supporting structures. In a world of constant eating and processed food, strategic extended fasting is one of the most powerful (and free) ways to trigger deep biological repair mechanisms our bodies evolved with. Have you ever tried a multi-day fast, or does 72 hours sound insane to you?

The Colorado Gators and Reptile Park hold a yearly Gators Fest. Check this out. It would be fun to watch but from a distance. Gatorfest is their annual “health day” for Colorado’s modern‑day dinosaurs. They head into the water, find the gators who need their yearly check‑up, jump them fast, walk them through the water, and bring them onto land for their exam. After that they check their chip, measure them, clean bites, and treat any infections so they stay healthy.

Warren Buffett reveals the most important decision you'll ever make in life "You'll go in the direction of the people that you associate with. The most important for most people in terms of that decision is their spouse. It's also important in terms of a partner in business, but the partner in life is the most important" "You want to pick a spouse that's a little better than you are, and then you hope they don't figure it out too fast"

$100k/m startup idea: People aren't going to stop eating fast food. So I built Cheat Day - an app that ranks every fast food so you always know the smartest thing to order. Designed in Figma. Built into a real app with Superapp AI in just a few hours. Would you use it?

Disney caved on Jimmy Kimmel because people around the world came out and used their voices in protest. It’s a really bad day for those who thought the cancellation was strictly a business decision.

Dr. Pradip Jamnadas gave the simplest, most powerful longevity hack most people ignore: “If you just want to be healthy, stay disease-free, avoid diabetes and modern illnesses—eat once a day, or at most twice a day in a 6–8 hour window.” That’s it. No complicated diets. No endless calorie counting. Practical example he gave: Lunch at 1 PM → dinner at 6–7 PM → nothing else. Zero snacking in between. Why? Every snack spikes insulin, breaks the fast, stops ketogenesis, and keeps your body in constant storage mode instead of repair mode. Time-restricted eating (once or twice a day) = general maintenance + fat loss + metabolic reset. If you tried eating only once or twice a day in a tight window… how many days did you last—and how did you feel?

RFK Jr. Before Robert Irvine came in, only a third of soldiers were eating in the cafeteria. "The food was so unspeakable, and they were going out and they were buying fast food at the local restaurant." "Fast food is not cheap. So they were spending their meager paycheck on fast food, which was not making them any healthier either." "And now there's there are lines around the block where people for soldiers trying to get in to get at this food that he's making." "Pentagon allocates in its food budget $18.50 per soldier per day. That's three meals for $18.50. He's now getting good food at $10.00."

This took place two years ago in Heide, Germany. It is only a three-minute excerpt from hours of torture of a German girl by a gang of migrants. When the mother saw the video, she almost collapsed! The girl is severely traumatized. The migrant torture gang got away with it because they were still “too young.” This happens every day in Germany. Most of the time, it is simply not filmed or published. Not to mention that on average, more than two gang rapes take place every day in Germany. At the same time, Germany has brutally crushed any attempt to organize patriotic resistance against migrant crime & population replacement for decades. -People who hang German flags are prosecuted. -People who criticize migration are prosecuted. -People who say that there is a German people and want remigration are persecuted as extremists. If this continues, will there be no German people left in 100 years? I ask the global public not to stop talking about what is being done to the German people! Remigration is our right.
